ONE HUNDRED YEARS OF PROGRESS 

The year 1986 is the centennial of the Research Branch, Agriculture Canada. 
On 2 June 1886, The Experimental Farm Station Act received Royal Assent. The passage of this 
legislation marked the creation of the first five experimental farms located at Nappan, Nova 
Scotia; Ottawa, Ontario; Brandon, Manitoba; Indian Head, Saskatchewan (then called the North- 
west Territories); and Agassiz, British Columbia. From this beginning has grown the current sys- 
tem of over forty research establishments that stretch from St. John's West, Newfoundland, to 
Saanichton, British Columbia. 

The original experimental farms were established to serve the farming community and assist the 
Canadian agricultural industry during its early development. Today, the Research Branch con- 
tinues to search for new technology that will ensure the development and maintenance of a com- 
petitive agri-food industry. 

Research programs focus on soil management, crop and animal productivity, protection and re- 
source utilization, biotechnology, and food processing and quality.

PREFACE 



The Agricultural Engineering Section of the Swift Current Research Station was 
established in the 1930's and has contributed significantly to providing new 
or modified research equipment to meet the needs of agricultural research 
scientists throughout the world. Information on the earlier developments in 
research equipment at this Station is given in the history of the Station 
entitled "Serving Seraiarid Agriculture". 

This publication brings together descriptions of more recent research equipment 
developments at the Swift Current Research Station. One of the objectives in 
producing this publication is to provide a more detailed historical 
record of the equipment developed here. For this reason the centennial year 
of the Research Branch was chosen for its first publication. The second 
objective of this directory is to provide a catalogue of available equipment 
that may be useful to researchers at other establishments. 

The loose-leaf format of this publication was chosen to enable page addition 
on an ongoing basis as new equipment is developed and described. New pages 
will be developed and printed for each piece of equipment developed in the 
future. These will be available by contacting the Swift Current Research 

Dr. N.B. McLaughlin and Mr. F.B. Dyck, design engineers in the Engineering 
Section of the Swift Current Research Station, provided the impetus that 
resulted in this publication. We hope you will find this publication useful.

SWIFT CURRENT SELF-PROPELLED PLOT SEEDER 




History : Original design by F.B. Dyck in 1968. Several models of the basic 
machine incorporating minor modifications have been built at the Swift Current 
Research Station and by local manufacturers. Used extensively at agricultural 
research institutions in Western Canada. 

Description : Self-propelled, front wheel drive, hydrostatic transmission, 
articulated steering with pivot point over front wheels. Can turn 90 degrees 
in either direction. One wheel on both the front and rear axles for each row 
to achieve uniform packing. Fitted with seed divider (see page A 2/86) and 
cone belt distributor (see page A 3/86). Most models fitted with a cab to 
permit operation in windy conditions. Separate fertilizer box provided. 
Different designs of furrow openers have been used.

STATIC SEED DIVIDER 




History : Original design by D. Penner in 1975 with later improvements by F.B. 
Dyck and N.B. McLaughlin. Used on Swift Current plot seeders. 

Description : Equally spaced holes, one for each row, are drilled at an angle 
into the divider body using a milling machine and indexing chuck. A fluted 
cone is formed inside the divider body where the holes intersect. Seed for an 
entire plot is dumped into the cup above the divider, and if necessary, 
manually leveled. A mirror is provided to aid the operator in determining if 
the seed is level. A solenoid operated gate opens to drop the slug of seed 
onto apex of the fluted cone. Seed is split equally and runs out attached 
plastic tubes to cone-belt distributors. The divider must be vertical for 
uniform division; a gimbal for the divider and cone-belt distributors was 
constructed to level the system for operation on hilly terrain (see page A 
4/86). 

Publication : None.

CONEBELT DISTRIBUTOR FOR PLOT SEEDERS 




History : Designed in 1976 by F.B. Dyck. Earlier designs of cone distributors 
employed a base attached to the cone, and a scraper mechanism to push the seed 
off the base. This required a close slide fit which was prone to plugging 
with dirt and subsequent siezing of the cone. 

Description : Seed for an entire plot is dropped into the cup on the top of 
the cone. The cup is then raised and seed falls down the surface of the cone 
and is trapped by the belt. The cone is ground driven and makes one revolution 
in the length of the plot. The belt is driven by the cone and leaves the 
cone to pass around the front roller releasing seed to fall by gravity into 
the seed tube to the furrow opener. The device is self cleaning with no seed 
carry over from one plot to the next. Also suitable for fertilizer and 
granular herbicides.

fourth conference of the International Association for Mechanization of Field 
Experiments, Iowa State University, Ames, Iowa, U.S.A. July 5-10, 1976.

CONE LEVELING SYSTEM FOR PLOT SEEDER 




History ; Designed by F.B. Dyck in 1978 as an accessory for the Swift Current 
self-propelled plot seeder (page A 1/86). Permits levelling of the cone 
distribution system when operating in hilly terrain thereby preventing excess 
seed on the downhill side of the cones. 

Description : Cone distribution system mounted on a gimbal is free to rotate 
about two horizontal axes. An electric actuator from an automobile power 
window (left) and an electric screw jack, (right) control the roll and pitch of 
the gimbal. Before releasing seed into the cone cups, the operator checks 
fisheye or spirit level bubbles on the gimbal and makes appropriate adjust 
ments to level the cones by manually operating two momentary switches control 
ling power to the two actuators. 

Publication : None.

SELF-PROPELLED PLOT SEEDER FOR FERTILIZER SIDE BANDING 




History ; Designed by F.B. Dyck in 1980 as a modification to the Swift Current 
Self-Propelled Plot Seeder. Used in the soil fertility program at Swift 
Current and Saskatoon, Saskatchewan; Brandon, Manitoba; Lacombe and Vegreville, 
Alberta. 

Description : Utilizes two independent tool bars and two sets of furrow 
openers. The rear set of openers can place both seed and fertilizer in the 
conventional manner, and can be set at desired seeding depth. The front set, 
which apply fertilizer only, can be set at any depth independent of the rear 
set, and can be shifted sideways to give a lateral offset with respect to the 
rear set. Fertilizer can thus be banded with the front set of openers at any 
position both horizontally and vertically with respect to the seed. 

Publication ; None. 

Availability : Plans are available from Research Station, Research Branch,

MICRO PLOT SEEDER 




History ; Designed by N.B. McLaughlin in 1976 and used in the cereal breeding 
program at the Swift Current Research Station. 

Description ; The micro plot seeder is an attachment for the Swift Current 
self-propelled plot seeder developed by F.B. Dyck. The device sows 0.5 m long 
plots perpendicular to the direction of travel. The furrow opener consists of 
two 0.5 m wide blades which are held tight together and forced into the soil 
with a hydraulic cylinder. The blades are then separated opening a 0.5 m long 
furrow. Seeds are dropped into the open furrow and the blades are withdrawn 
and then brought back together in preparation for the next plot. The furrow 
opener movements and the seed dropping mechanism are automatic and are 
synchronized to ground speed to achieve a plot spacing of 23 cm. Seeding 
capacity is about 500 plots per hour. About 20 kernels of wheat are sown in 
each plot, and there is no seed carry over from one plot to the next. Border 
rows parallel to direction of travel can be sown at either end of the micro 
plots with the outside double disk openers on the self-propelled plot seeder.

SWATHER STUBBLE DEFLECTOR FOR CREATING SNOW TRAP BARRIER STRIPS 




History ; Designed by F.B. Dyck and H. Steppuhn. Used to create stubble 
barriers in snow management studies at the Swift Current Research Station and 
by local farmers. 

Description : Deflector attachment is constructed from mild steel rod and 
bolts onto the cutter bar of a conventional swather. Several rows of grain 
are deflected sideways so the cutter bar severs the stalks higher on the plant 
than those for the remainder of the swather width. The longer stubble springs 
back after the swather passes, leaving a stubble barrier strip for subsequent 
snow trapping.

AUTOMATIC WATER DISPENSER FOR POTTED PLANTS 




History ; Designed by F.B. Dyck in 1973. 
Station, Regina Saskachewan . 



Used at the Agriculture Canada Research 



Description : Consists of a laboratory beam balance fitted with a limit switch 
and a photoelectic controller, and a pair of solenoid valves (high and low 
flow) connected to a carboy reservoir. Pots are placed on the balance one at: 
a time and the solenoid valves opened by pressing a start button. Water flows 
by gravity through the valves, and when the pot reaches a predetermined 
weight, the balance beam actuates the limit switch and the high flow valve 
shuts off. Water Is gradually added through the low flow valve and when the 
pot reaches the final preset weight, a light beam is interrupted and the 
photoelectric controller shuts off the low flow valve. Amount of water added 
is calculated from the difference between the initial and final pot weights.

SEMI-AUTOMATIC POT WATERING DEVICE 




History: Designed by N. B. McLaughlin in 1976 based on an earlier design by 
F.B. Dyck. Used at Agriculture Canada Research Stations in Swift Current, 
Regina, and Brandon, and at the CIDA project in Brazil. 

Description: Consists of a direct reading dial scale fitted with a photo 
electric pickup, a control box, a centrifugal pump, and a pair of solenoid 
valves. The operator manually places potted plants on the scale, one at a 
time, and presses a "start button". After a short time delay to allow the 
scale to settle, the valves automatically open dispensing water into the pot. 
When the pot reaches a predetermined weight, the scale dial interrupts a light 
beam and the valves automatically close shutting off the flow of water. The 
quantity of water added can be readilly determined from the difference between 
the initial and final weight of the pot. Repeatability of the final weight is 
within ± 1 gram.

100-CELL SEED GERMINATOR 




History : Designed by N.B. McLaughlin in 1977 and used at the Agriculture Canada 
Research Station, Regina Saskatchewan to study germination response of weeds 
under alternating temperature regimes. 

Description : The 100- cell seed germinator is capable of simultaneously gener 
ating 100 different diurnal temperature cycles with extremes lying between 
and 45 C. Each cell can accept a 100-mm Petri dish to hold seeds and is 
fitted with a glass cover to allow entry of light essential for germination of 
certain species. Each cell is equipped with an independent electronic 
temperature controller employing a thermistor for temperature sensing. Diurnal 
temperature cycling is achieved by switching different reference resistors 
corresponding to different temperatures into the circuits at appropriate times 
in a 24-hour period. Heating or cooling of the cells is accomplished by 
thermo-electric heat pumps, one for each cell.

RAIN SIMULATOR 




History : Designed in 1982 by T.N. McCaig with input from F.B. Dyck. Based on 
an earlier design by McMaster and Derera (Cereal Research Communications 4: (2) 
251-254 1976). Used in wheat breeding programs at Agriculture Canada Research 
Stations in Swift Current Saskatchewan and Beaverlodge Alberta to study sprouting 
resistance of breeding lines. 

Description : A series of screen bottom trays are suspended from a rotating 
wheel similar to a Ferris Wheel. Harvested whole plant material is laid on 
the trays to simulate a swath. The wheel is rotated at about 0.5 rpm passing 
the trays under a series of spray nozzles to simulate intermittent rain. 
Troughs made from polyethylene film are placed under the trays to carry water 
perculating through the plants to the end of the trays so that it doesn't fall 
directly onto plants on the tray below. The simulator is placed In a temperature 
controlled cabinet to achieve environmental control.

A MICROCOMPUTER CONTROLLED LEAF-WEIGHING SYSTEM 



Motor a Georboi 



Note-Hinged Bock 8 Sid. 




History : Designed by T.N. McCaig. Used in drought physiology studies at the 
Swift Current Research Station to monitor the rate of moisture loss from wheat 
plant leaves under controlled conditions. 

Description : Leaves are removed from growing plants and attached to hangers 
on an endless conveyor chain. A microcomputer controls movements of the 
conveyor chain stopping the chain when a leaf is adjacent to a weigh station. 
A transfer mechanism, also controlled by the computer, lifts the leaf off the 
conveyor chain and places it on an electronic balance. After weighing, the 
transfer mechanism replaces the leaf on the conveyor chain and the chain is 
advanced to deliver the next leaf to the weigh station. Weights are logged by 
the computer and stored on diskette. Rate of water loss can be calculated 
from multiple weighings of each leaf over a period of time. The system has a 
capacity of 265 leaf samples and can automatically weigh each sample five 
times in an 8-hour day.

LABORATORY BARLEY MALTER 




History : Designed in 1983 by N.B. McLaughlin, and based on an earlier design 
by Atkinson and Bendelow (Can. J. Plant Sci. 56:1007-1010). Used in the 
cereal quality program at the Agriculture Canada Research Station, Winnipeg 
Manitoba. 

Description : The malter consists of an insulated stainless steel cabinet 
fitted with a thermostatically controlled refrigeration system. Barley 
samples (40 gram) are placed in 250 ml perforated plastic jars and clipped to 
the periphery of a low speed horizontal rotor. The rotating action gently 
tumbles the barley and prevents matting during the malting process. Samples 
are subjected to alternate steep and air cycles, the time in each cycle being 
automatically controlled by a program on a seven day time clock. In the steep 
cycle, the barley is submersed in water permitting uptake of water. In the 
air cycle, the barley is held in a humid atmosphere permitting germination 
utilizing residual moisture and accompanying respiration. Capacity of the 
malter is 126 samples per run.
